Senior Backend / Full-Stack Engineer · 10+ Years Experience · Remote-First

I design, build, and operate backend systems that scale in real-world production environments.
Over the past decade, I've architected APIs, debugged high-pressure production issues, and shipped features that directly impacted business metrics and operational reliability.

My experience spans enterprise platforms and SaaS products — from data modeling and RESTful API design to containerized deployments and post-release monitoring. I'm comfortable owning the full software lifecycle: requirements, implementation, testing, deployment, and long-term maintenance.

I work best in small, autonomous teams where engineers own their systems end-to-end.
Currently open to remote, async-first SaaS teams.

• Designing and building production-grade RESTful APIs and microservices
• Node.js (Express), Python, PHP (Laravel, Symfony), C# (.NET)
• Relational & NoSQL data modeling and performance optimization
  (PostgreSQL, MySQL, MongoDB, SQL Server)
• Debugging, incident response, and root-cause analysis in production

• Frontend integration with Angular and React
• End-to-end feature ownership: database → API → UI
• Third-party integrations, webhooks, and external service orchestration

• Docker-based containerization and deployments
• Git workflows, CI/CD pipelines, and release automation
• IoT system integration (Raspberry Pi, Arduino, Android)

• Architected and delivered production systems supporting business-critical workflows
• Built scalable backend services with structured error handling, logging, and monitoring

• Designed REST APIs consumed by web and mobile clients
• Implemented integrations with third-party services and payment systems

• Delivered end-to-end IoT solutions connecting hardware sensors to cloud backends
• Built data pipelines for near real-time device monitoring and analytics

Detailed code samples and repositories are available below in pinned projects.

• Ownership — I take features from concept to production and support them afterward
• Production Mindset — I design systems that fail gracefully and are debuggable at 2 AM
• Clear Communication — I document decisions, write readable code, and align with stakeholders
• Pragmatism — I choose the right tool for the problem, not the trendiest one
• Autonomy — Comfortable owning ambiguous problems and turning them into shipped systems

I'm interested in Senior Backend or Full-Stack roles at SaaS companies, startups, and remote-first teams.
